Turning off vSphere Fault Tolerance deletes the secondary virtual machine, its configuration, and all history.

Use the Turn Off Fault Tolerance option if you do not plan to reenable the feature. Otherwise, use the Suspend Fault Tolerance option.

Note: If the Secondary VM resides on a host that is in maintenance mode, disconnected, or not responding, you cannot use the Turn Off Fault Tolerance option. In this case, you should suspend and resume Fault Tolerance instead.


  1. In the vSphere Client, browse to the virtual machine for which you want to turn off Fault Tolerance.
  2. Right-click the virtual machine and select Fault Tolerance > Turn Off Fault Tolerance.
  3. Click Yes.


Fault Tolerance is turned off for the selected virtual machine. The history and the secondary virtual machine for the selected virtual machine are deleted.
Note: Fault Tolerance cannot be turned off when the secondary VM is in the process of being started. Since this involves syncing up the primary VM's full state to the secondary VM, this process may take longer than expected.
